Skateboard bushings

Selection of Bushings for Skateboard Trucks.\nI 3D printed several bushings using Ninjaflex at a 100% infill setting, and they felt remarkably similar to extra soft skateboard bushings initially, but I'm unsure how long they will endure.\nUpdate: Following some quick research on Ninjaflex, it appears to have a hardness rating of 85A, which is significantly closer to Bones' soft bushings at 81A. In comparison, Semiflex has a hardness of 98A, while Bones' hard bushings clock in at 96A. Notably, Ninjaflex is also classified as a thermoplastic polyurethane, the same material used in skateboard wheels and bushings, so it should be suitable for printing solidly. Theoretically, this means you can create some pretty decent wheels using Semiflex.\nI suspect that I may have compromised some of the hardness due to the print quality of my bushing.\nProceed with caution is advised.
